Although the V90 is an entry-level machine, itโs decidedly not a toy. The way it functions is complicated โ a platform carries the tool holder; a larger gantry moves the tool back and forth; the frame positions the gantry; and itโs all driven by a motor turning the screw interposed between two shafts. Indeed, this three-axis Cartesian robot is probably the most complex machine Iโve ever built, and I had expected it to be correspondingly difficult to assemble; however, quite the contrary โ itโs easier than many common bike repairs. A thriving community actively updates the online build guide, and all the materials were very helpful during my own build.
